.. note:: If :ref:`RBAC <c3_rbac_manage_roles_ui>` is enabled, you must have permissions to delete a topic.

When you request to delete a topic, the topic is marked for deletion. 
The topic is not deleted immediately unless it is devoid of data, 
such as a newly created topic. In the interim, you cannot recreate 
a topic with the same name as the topic being deleted until the original topic 
and its data is finished being deleted.
